Education

  1. University of Torino (Italy), Veterinary Sciences (focus on Basic Sciences and Veterinary Biotechnology), Ph.D., 2010
  2. The Pennsylvania State University, Visiting Scientist, 2007-2008
  3. University of Torino (Italy), Veterinary Biotechnology, B.S., 2003

Research Interests:

Investigate and understand the diversity and distribution of pathogenic bacteria across different sources by the development and application of novel molecular subtyping methods.  Utilize these methods to track both  pathogenic bacteria, such as Listeria monocytogenes,  E. coli O157:H7 and Salmonella and spoilage microorganisms (E. coli, Pseudomonas, Bacillus) isolated from foods and food production environments. ).  Conduct research on the prevalence of Listeria spp., Bacillus spp. and Escherichia coli in packaged animal feed for use in dairy herd and along the food supply chain,  to identify  persistent strains and develop strategies for their control. Develop  multiplex SNP-based assays for molecular subtyping of beneficial bacteria such as Bifidobacterium animalis subspecies lactis strains.

Courses Taught:

Adding Value to Traditional Products of Regional Origin (16 hrs - 2 CFUs*); New Analytical Methods Applied to Foods (24 hrs - 2 CFUs*); Biotechnology Applied to the Production and Control of Food (8 hrs); Molecular Methodologies for the Detection of Contamination along the Food Supply Chain (8 hrs); Hygiene in Food Production (lab course): Microbiology of Food and Animal Feeding Stuffs (30 hrs).
*CFU: University learning credit, one usually corresponds to 25 hours of work, including lessons, lab work, etc., as well as home study.
Languages: Fluent in English. Italian mother tongue.
